West Texas Intermediate Spot Price
West Texas Intermediate (WTI) is a Texas light sweet grade of crude oil used as a standard in oil pricing. It is described as light because it has a comparatively low density, (API gravity of around 39.6 and specific gravity of about 0.827) and because of its low sulfur content is called sweet (less than 0.42% sulfur).
Light sweet crude oil is the preferred crude oil for processing into gasoline (naphtha), kerosene, and high-quality diesel.
It is the underlying commodity of Chicago Mercantile Exchange's oil futures contracts. WTI is often referenced alongside the price of Brent crude from the North Sea. Other oil markets are the Dubai Crude, Oman Crude, Urals oil and the OPEC Reference Basket.
WTI is lighter and sweeter than Brent, and by far lighter and sweeter than Dubai or Oman.
